The Guinness share-trading fraud was a major business scandal of the 1980s. It involved the manipulation of the London stock market to inflate the price of Guinness shares to thereby assist Guinness's £4 billion takeover bid for the Scottish drinks company Distillers . Four businessmen were convicted of criminal offences for taking part in the manipulation. The scandal was discovered in testimony given by the US stock trader Ivan Boesky as part of a plea bargain . Ernest Saunders , Gerald Ronson , Jack Lyons and Anthony Parnes , the so-called Guinness four , were charged, paid large fines and, with the exception of Lyons, who was suffering from ill health, served prison sentences. The case was brought by the Serious Fraud Office .
65-477: The defendants bought shares in Guinness plc to enable Guinness (by supporting its share price) to take over Distillers , a much larger company. The Distillers board favoured Guinness as partners and were facing a hostile bid by Argyll . The Guinness executives guaranteed without limit the defendants' losses if the value of their Guinness shares dropped; this gave the defendants an unfair advantage in what should be

Arthur Guinness started selling the dark beer porter in 1778. The first Guinness beers to use the term "stout" were Single Stout and Double Stout in the 1840s. Throughout the bulk of its history, Guinness produced only three variations of
195-441: A brief period in 1997. In 2017, Diageo made their beer suitable for consumption by vegetarians and vegans by introducing a new filtration process that avoided the use of isinglass from fish bladders to filter out yeast particles. Guinness stout is made from water, barley , roast malt extract, hops , and brewer's yeast . A portion of the barley is roasted to give Guinness its dark colour and characteristic taste. It
260-603: A fair market. The prosecution relied on a new law; the defendants claimed that supporting a share price with a guarantee was an unusual but longstanding market practice. Saunders had invested US$ 100 million with an American arbitrage expert, Ivan Boesky , to invest in shares; Boesky stated that the fee for managing this amount was his reward for supporting the Guinness share price. Boesky was charged in New York on another matter and mentioned this payment under questioning. This information

With the move to nitrogen gas dispensing in the 1960s, it was felt important to keep the two-stage pour ritual in order to bring better consumer acceptance of the change. As Guinness has not been cask-conditioned for decades, the two-stage pour has been labelled a marketing ploy that does not actually affect
390-570: A move as a rumor, but as speculation mounted in the wake of the Sunday Independent article, the company confirmed it was undertaking a "significant review of its operations". This review was part of the company's ongoing drive to reduce the environmental impact of brewing at the St. James's Gate plant. On 23 November 2007, an article appeared in the Evening Herald , a Dublin newspaper, stating that

In October 2010, Guinness began selling Foreign Extra Stout in 4 packs of bottles in the United States. In 2014, Guinness released Guinness Blonde , a lager brewed in Latrobe, Pennsylvania using a combination of Guinness yeast and American ingredients. When Guinness opened their new brewery in Baltimore, Maryland in August 2018 they recreated "Blonde" to "Baltimore Blonde" by adjusting

Several UK firms have made
585-448: A public company and was averaging sales of 1.138 million barrels a year. This was despite the brewery's refusal to either advertise or offer its beer at a discount. Even though Guinness owned no public houses , the company was valued at £6 million and shares were 20 times oversubscribed, with share prices rising to a 60 per cent premium on the first day of trading. The breweries pioneered several quality control efforts. The brewery hired
650-533: A single beer type: porter or single stout, double or extra and foreign stout for export. "Stout" originally referred to a beer's strength, but eventually shifted meaning toward body and colour. Porter was also referred to as "plain", as mentioned in the famous refrain of Flann O'Brien 's poem "The Workman's Friend": "A pint of plain is your only man." Already one of the top-three British and Irish brewers, Guinness's sales soared from 350,000 barrels in 1868 to 779,000 barrels in 1876. In October 1886, Guinness became

Casks newly delivered to many small pubs were often nearly unmanageably frothy, but cellar space and rapid turnover demanded that they be put into use before they could sit for long enough to settle down. As a result, a glass would be part filled with the fresh, frothy beer, allowed to stand
845-399: A takeover advisor, never came to trial. The case against Spens and Seelig collapsed in 1992 and charges against Mayhew were dropped after pre-trial challenges by his lawyers. Another defendant, Ward, returned to Britain to stand trial and was acquitted of any dishonesty. Though acquitted, the defendants had to pay lawyers' fees. The Department of Trade and Industry finally released in 1998
910-422: Is pasteurised and filtered . Until the late 1950s, Guinness was still racked into wooden casks. In the late 1950s and early 1960s, Guinness ceased brewing cask-conditioned beers and developed a keg brewing system with aluminium kegs replacing the wooden casks; these were nicknamed "iron lungs". Until 2016 the production of Guinness, as with many beers, involved the use of isinglass made from fish. Isinglass

1040-413: Is a relatively modern addition that became part of the grist in the mid-20th century. For many years, a portion of aged brew was blended with freshly brewed beer to give a sharp lactic acid flavour. Although Guinness's palate still features a characteristic "tang", the company has refused to confirm whether this type of blending still occurs. The draught beer 's thick, creamy head comes from mixing

1170-470: Is now prohibited in Ireland. A 2003 study found that stouts such as Guinness could have a benefit of helping to reduce the deposit of harmful cholesterol on artery walls. This was attributed to the higher levels of antioxidants in stouts than in lagers, though the health benefits of antioxidants have been called into question, and Diageo, the company that now manufactures Guinness, said: "We never make any medical claims for our drinks." Guinness stout

1625-508: The British forces. Over 800 employees served in the war. This was made possible due to a number of measures put in place by Guinness: soldiers' families were paid half wages, and jobs were guaranteed upon their return. Of the 800 employees who fought, 103 did not return. During World War II , the demand for Guinness among the British was one of the main reasons why the UK lifted commerce restrictions imposed in 1941 to force Ireland into supporting
1690-563: The Dublin City Council, in the best interests of the city of Dublin, had put forward a motion to prevent planning permission ever being granted for the development of the site, thus making it very difficult for Diageo to sell off the site for residential development.

2470-471: The fundamental texture and flavour of the Guinness of the past as nitrogen bubbles are much smaller than CO 2 , giving a "creamier" and "smoother" consistency over a sharper and traditional CO 2 taste. This step was taken after Michael Ash —a mathematician turned brewer—discovered the mechanism to make this possible. Nitrogen is less soluble than carbon dioxide, which allows the beer to be put under high pressure without making it fizzy. High pressure of

2860-497: The old ones. Guinness recommends that, to avoid the bitter taste of the nitrogen foam head, gulps should be taken from the glass rather than sipping the drink.

As beer rises in the centre, the beer near the outside of the glass falls. This downward flow pushes the bubbles near the glass towards the bottom. Although the effect occurs in any liquid, it is particularly noticeable in any dark nitrogen stout, as the drink combines dark-coloured liquid and light-coloured bubbles.
